Before you start the walk: there is also a nice small waterfall north (400 m) of the parking called Rhaedr Ogwen. Not very tall but the scenery is perfect. Now the walk: from the parking keep left (east of the river), there is a trail going to lake Llyn Idwal.

At the end of the lake you go uphill, the trail bend slightly to the right and now you are heading to Devil’s kitchen, another nice waterfall situated in a small gorge. Here you cross the river and via the base of Devil’s Appendix return back along the other side of the lake to the car. The walk takes about 1,5-2 hours (4,5 kilometers).
